There are three basic types of light switches used in the home: single-pole, 3-way, and 4-way switches. The single-pole switch is used when one or more lights are to be controlled from a single location. The 3-way switch is used in pairs when one or more lights are to be controlled from two locations. The 4-way switch is used in combinations with two 3-way switches when one or more lights are to be controlled from three or more locations. The terminology used with these switches may sound daunting but the actual wiring is straight-forward and simple. Turn off the circuit breaker supplying power to the switch circuit that you will be working on.
Three-way switches require a three-wire cable: the power wire, the neutral wire, and the traveller or switch wire. The cable should also have a ground wire, or a total of four wires in the cable. The system also requires three-way switches. The switches are wider than regular single-pole switches and they have three terminal screws on the side sometimes back of the switch housing.
By code, the number of conductors allowed in a box are limited depending on box size and wire gauge. Calculate total conductors allowed in a box before adding new wiring, etc. Check local regulations for restrictions and permit requirements before beginning electrical work.

I have a single gang box in a bathroom with a GFCI outlet. I'd like to replace it with a 2-gang box containing a GFCI outlet and a light switch for the vanity light. The outlet will have both receptacles live not switched.
